The Federation of Jewish Religious Communities of Rumania is operating holiday resorts and convalescent homes with accommodations for 500 persons, Dr. Moses Rosen, Chief Rabbi of Rumania, reported here. He told JTA that the holiday resorts are patronized by students and young intellectuals who may attend courses in Hebrew, Jewish studies and Jewish music, both religious and popular. He said the courses are given by resident instructors and visiting lecturers. Rabbi Rosen said the resorts and convalescent homes offer kosher cuisine.
